Add optional Kconfig setting to delay scanning after each output column is set, and inputs are read, to allow inputs to "settle" after the last column is set back to inactive.

When iterating over each output to drive it active, read inputs, then set
|
|
inactive again, some boards may take time for the previous output to
|
|
"settle" before reading inputs for the next active output column. In that
|

scenario, set this value to a positive value to configure the number of
|
|
usecs to wait after reading each column of keys.
